Wisconsin and Alabama turned their conference showdowns into mismatches.

Behind Russell Wilson, the seventh-ranked Badgers erased an early deficit and pounded eighth-ranked Nebraska 48-17 in the Cornhuskers' first Big Ten game Saturday night.

Trent Richardson was the star for No. 3 Alabama, which knocked Florida quarterback John Brantley out of the game late in the first half and routed the 12th-ranked Gators 38-10.

On the first Saturday of October, the national championship race got some clarity with the teams at the top of the rankings asserting their dominance.

Wilson accounted for three touchdowns and has emerged as a Heisman Trophy contender. Same goes for Richardson, who set a career best with 181 yards rushing.

The Badgers, the defending Big Ten champions, could see Nebraska again at the conference title game.

The Crimson Tide and Gators could also be paired up down the road in a league championship game.

But the gap between the Badgers and Tide and the Huskers and Gators was huge Saturday.

No. 1 LSU 35, Kentucky 7

BATON ROUGE, La. — Jordan Jefferson scored on his first play back from suspension and cornerback Tyrann Mathieu scored after setting an LSU record for career forced fumbles.

Jefferson was reinstated this week after a grand jury reduced his charges in connection with a bar fight to a misdemeanor. Jarrett Lee remained the starter at quarterback.

LSU coach Les Miles inserted Jefferson on an early fourth-and-goal, and Jefferson dove over the goal line to give the Tigers (5-0, 2-0 SEC) a 7-0 lead. Lee later hit Odell Beckham Jr. for a 51-yard score, their second TD connection of more than 50 yards in two games.

Kentucky (2-3, 0-2) did not threaten to score until LSU led 35-0.

No. 2 Oklahoma 62, Ball State 6

NORMAN, Okla. — Landry Jones threw for 425 yards and five touchdowns, Tony Jefferson fueled a second-quarter scoring surge with three interceptions and Oklahoma geared up for Texas.

Jones had touchdown passes of 64 yards to Ryan Broyles and 56 yards to Jaz Reynolds a minute apart in the third quarter during the second high-volume scoring stretch for the Sooners (4-0).

Ball State (3-2) didn't stand much of a chance after recovering an onside kick to open the game, then going three-and-out. Jefferson stopped three straight Cardinal drives with picks midway through the second quarter.

No. 3 Alabama 38, No. 12 Florida 10

GAINESVILLE, Fla. — Trent Richardson ran for 181 yards and two touchdowns, breaking tackles and carrying defenders along the way, and Alabama rolled in an early season matchup of Southeastern Conference heavyweights.

Richardson finished with his fourth consecutive 100-yard game, and the latest one should solidify his position as one the Heisman Trophy front-runners.

With Richardson leading the way, the Crimson Tide (5-0, 2-0 SEC) extended its recent dominance in the series. Alabama has outscored the Gators (4-1, 2-1) 101-29 in three wins in as many seasons.

The latest one was over by halftime.

Florida struck first, getting a 65-yard touchdown pass from John Brantley to Andre Debose. It was one of few highlights for the Gators, who couldn't run, couldn't stop the run and lost Brantley to a right leg injury late in the second quarter.

No. 4 Boise State 30, Nevada 10

BOISE, Idaho — Doug Martin ran for two touchdowns and Boise State's suffocating defense shut down Nevada's potent offense.

Boise State's defense dominated throughout the game and prevented the Wolf Pack (1-3) from crossing midfield until midway through the third quarter.

Martin rushed for 126 yards on 21 carries, and his 43-yard touchdown run early in the third quarter put the Broncos (4-0) up 27-0. His best game of the season helped offset a lackluster performance by Kellen Moore and the rest of the Boise State offense.

Moore threw two touchdowns, but was also intercepted on back-to-back possessions in the second quarter. Moore's second touchdown pass gave him 113 in his career, moving past Colt McCoy of Texas for eighth best all-time.

No. 7 Wisconsin 48, No. 8 Nebraska 17

MADISON, Wis. — Russell Wilson gave Nebraska a harsh welcome to the Big Ten.

Montee Ball ran for 151 yards and four touchdowns for the Badgers (5-0, 1-0 Big Ten). But Wilson was the main attraction for a prime-time television audience as Wisconsin overcame a slow start to solidify its status as the class of the conference.

Wilson was 14 for 20 for 255 yards.

Taylor Martinez threw three interceptions for the Huskers (4-1, 0-1), who showed they weren't quite ready for the best of the Big Ten.

Auburn 16, No. 10 South Carolina 13

COLUMBIA, S.C. — Barrett Trotter threw a 9-yard touchdown pass to Phillip Lutzenkirchen with 1:38 left to lift Auburn.

The Tigers (4-1, 2-0 Southeastern Conference) had struggled to move the ball against South Carolina's defense. Trotter had thrown two interceptions and was sacked four times by the Gamecocks (4-1, 2-1). But down 13-9, Barrett led Auburn on a 12-play, 57-yard drive that ended with a pass to wide open Lutzenkirchen in front of the goal line.

The junior fumbled the ball into the end zone, then recovered it just before sliding out of bounds to put Auburn ahead.

South Carolina advanced to Auburn's 29 on its final possession before time expired, though Gamecocks coach Steve Spurrier argued that clock should have stopped with 1 second left after a completed pass for a first down.

Michael Dyer ran for 141 yards on a career-high 41 carries and had a 1-yard TD for Auburn, which has won its past 11 SEC games.

No. 17 Texas 37, Iowa State 14

AMES, Iowa — Freshman David Ash threw for 145 yards and his first two career touchdown passes and Texas won its Big 12 opener.

Jaxon Shipley added 141 yards receiving and a TD for the Longhorns (4-0, 1-0 Big 12), who raced out to a 34-0 halftime lead to beat the previously unbeaten Cyclones (3-1, 0-1).

Ash threw a 48-yard TD pass to Mike Davis and a 40-yard touchdown to Shipley, and Josh Turner took a blocked punt back 34 yards to help Texas blow the game open in the second quarter.

Steele Jantz was 28 of 51 passing for 251 yards and a late TD pass for Iowa State, which looked nothing like the team that stunned Texas 28-21 last season.

No. 18 Arkansas 42, No. 14 Texas A&M 38

ARLINGTON, Texas — Tyler Wilson and Jarius Wright shattered school records for passing and receiving, and Broderick Green ran 3 yards for the go-ahead touchdown with 1:41 left as Arkansas gave Texas A&M a preview of what it can expect from the SEC.

The Razorbacks (5-1) trailed by 18 at halftime, and hadn't led before Green squeezed through the left side of the line.

This makes two straight weeks the Aggies (2-2) have thrown away a huge halftime lead. They were up by 17 at home against Oklahoma State last week.

Wilson was 30 of 51 for 510 yards and three touchdowns, and ran for a 2-point conversion that tied the game at 35.

Wright caught 13 passes for 281 yards and two touchdowns.

Christine Michael ran for 230 yards and three touchdowns for A&M, but was stuffed on a fourth down to end his team's last chance.

No. 19 Michigan 58, Minnesota 0

ANN ARBOR, Mich. — Denard Robinson threw two touchdown passes and ran for a TD to lead Michigan to its most-lopsided win since 2000.

Vincent Smith scored on a run, pass and catch to help Michigan (5-0, 1-0 Big Ten) lead 38-0 at halftime.

Robinson was 15 of 19 for 169 yards and didn't throw an interception for the first time since the opener and had a season-low six rushing attempts for 51 yards. He was taken out in the third quarter.

Freshman Max Shortell made his first start for the Gophers (1-4, 0-0) in place of MarQueis Gray, who missed the game with an injured toe on his left foot.

The Wolverines kept the Little Brown Jug trophy that the teams have played for since 1909.

SMU 40, No. 20 TCU 33, OT

FORT WORTH, Texas — J.J. McDermott threw a 19-yard touchdown pass to Jeremy Johnson in overtime and SMU recovered from a fourth-quarter comeback for an upset.

The loss ended a school-record 22-game home winning streak for the Horned Frogs (3-2).

SMU (4-1) coughed up a 16-point lead in the fourth quarter before McDermott hit Johnson on a deep out route in the end zone for his fourth scoring toss of the game.

TCU's bid to tie ended when a tipped pass from Casey Pachall bounced off the chest of Brandon Carter just past the first-down marker.

The Mustangs beat a ranked opponent for just the second time since the NCAA imposed the so-called death penalty nearly 25 years ago.

No. 21 Georgia Tech 45, North Carolina State 35

RALEIGH, N.C. — Orwin Smith rushed for three touchdowns and Georgia Tech extend its best start in more than 20 years.

Smith finished with 74 yards and scored on runs of 13, 9 and 3 yards to help the Yellow Jackets (5-0, 2-0 ACC) open with five wins for the first time since their national championship season in 1990.

Georgia Tech led 21-0, briefly allowed N.C. State to make a game of it in the third quarter and pulled away with three touchdowns in a 2-minute, 22-second span of the fourth.

Mike Glennon was 20 of 29 for 163 yards with touchdown passes covering 9 yards to Jay Smith and 1 yard to Tyler Purvis. The Wolfpack (2-3, 0-2) remained winless against FBS teams.

No. 22 West Virginia 55, Bowling Green 10

MORGANTOWN, W.Va. — Freshman Dustin Garrison rushed for 291 yards and two touchdowns to lead West Virginia.

West Virginia's Geno Smith continued his solid season by throwing for three scores. But for the first time, the Mountaineers (4-1) found balance in their offense.

West Virginia entered the game as one of the worst rushing teams in the FBS with 306 total yards. The Mountaineers compiled 360 yards on the ground Saturday.

West Virginia held the Mid-American Conference's highest-scoring offense to 217 total yards. The Falcons (3-2) entered the game averaging 38.5 points.

No. 24 Illinois 38, Northwestern 35

CHAMPAIGN, Ill. — Quarterback Nathan Scheelhaase scored a 1-yard touchdown with 13 seconds left to lead Illinois to a comeback win.

Comment on this story

The sophomore threw for a career-high 391 yards and three touchdowns for the Illini (5-0, 1-0). All three TD passes went to A.J. Jenkins, who had 12 catches for a school-record 268 yards.

Scheelhaase had to engineer two comebacks to pull out the win over the Wildcats (2-2, 0-1).

Illinois scored 21 straight points after Northwestern took a 28-10 third-quarter lead. Then Scheelhaase scored the game-winning touchdown after a late touchdown run by Jacob Schmidt gave the Wildcats a 35-31 with just over a minute to play.

Wildcats quarterback Dan Persa played his first game in almost a year after tearing an Achilles' tendon. He finished 10 of 14 for 123 yards and four touchdown passes, but he left late in the fourth quarter when his leg stiffened.
